FORMER-HEAD FOR GLASS JARS.

SPECIFICATION forming part of Letters Patent No 341,317, dated May 4, 1886;

Application filed July 9, 1885. Serial No. 170,936. (No model.)

Figure 1 is a central sectional view of my improved former-head for glass jars, and Fig.

2 perspective view of the same.

In forming glass jars with a circumferential recess within an outer wall of the groove to hold the lid and cement, difficulty is sometimes 1 experienced in accomplishing this purpose in a smooth, even, and rapid manner. In order to accomplish this, I provide a former-head to fit within the opening of the jar provided on its upper surface with a pair of sliding pieces having springs attached thereto, each sliding piece having a right-angled formerso disposed as to have a bearing against the wall of the jar, and by rotating the same a suitable recess may be formed, all of which will now be set forth in detail.

In the accompanying drawings, A represents the former-head, provided with the peripheral rabbet B and having the usual vertical stem, 0, centrally disposed. The upper face of the 0 former-head A is provided with a pair of sliding pieces, D and E, the one resting on the other, and provided near its ends with ways or keepers F, so that they may move freely backward and forward within this said keeper.

These are centrally disposed within the said former-head A, and have slots G midway be tween the ends to receive therein the stem 0.

Secured to the stem 0 some distance above the head A, I provide a pair of springs, H and 0 I, oppositely disposed upon the said stem.

The lower end of one of these springs, H, enters the slot G within the sliding pieces D and E, and is secured to the shoulder of the sliding piece D, so that when the said sliding piece is 5 in its normal position it will be pushed laterally, as shown by the dotted lines J. The op posite spring, I, enters the slot G, and is secured to the shoulder of the upper sliding piece, E, so that when this piece E is in its normal position it will be moved out laterally, as shown by the dotted lines K.

Near the ends and beneath the sliding pieces D and E, I provide right-angled recesses L in the former-head, and within these recesses right-angled formers M and N are provided. One of the right-angled formers, M, is secured in any suitable manner to the lower sliding piece, D,whi1e the opposite rightangled former is secured to the upper sliding piece, E, and operating through a slot, 0, through the lower sliding piece, D.'

WVhen the sliding pieces D and E, carrying the rightangled formers M and N, arein their normal position, the said formers M and N are resting back in the recesses L, as shown by dotted lines 1?,so that when theprojecting ends J and K of the sliding pieces D and E are pressed against, when it is desired to operate the device, the sharpened ends of the rightangled formers M and N will project into the rabbet B.

The operation of this device is extremely simple. The former-head A is designed to be placed within the opening of the jar with the rabbet Bin close connection with the inner wall of the cement-groove of the jar. This brings the outer horizontal part of theformers opposite to the said inner wall of the groove and in close connection therewith. Then by pressing against the ends J and K of the adjustable sliding pieces D and E, so as to force the formers outwardly and rotate the entire former-head or jar, a circumferential groove is formed within the head of the jar. As this operation is designed to be performed immediately after the jar is molded and while the metal is still plastic, a single revolution of the head or jar is all that is necessary, when by releasing the pressure against the ends Jand K of the sliding pieces D and E the springs H and I return the sliding pieces and formers to their original position, when the formerhead may be removed from the jar. \Vhat I claim as new is 1. In a former-head for glass jars, a-pair of adjustable sliding pieces one over the other and secured in position by means of ways, one of them having a right-angledformer operating in a right-angled recess within the formerhead, and the other having a former operated through both a slot in the under sliding piece and a right-angled recess within the formerhead, in connection with the curved springs extending through the same, substantially as 3. The combination of the former-head A, having the circumferential rabbet B, the stem 20 C, the sliding pieces D and E, the curved connecting springs H and I, the recesses L, and the right-angled-formers M and N, operating therein, the whole arranged as and for the purpose substantially as herein set forth and de- 2 5 scribed.

In testimony that I claim the foregoing I have hereunto set my hand, this 17th day of June, 1885, in the presence of witnesses.
